Dude! Did you and Sasha flip the hippo last night? You were gone for hours!

Sorry I couldn't hang out yesterday, I was really sore from flipping the hippo with O'Glory.

I was thinking we could do something special tonight... Maybe some white wine, some turkey, we could flip the hippo--what do you say Willis?
